  This procedure is designed to help explore the number-theory problem
  in which an integer is added to its (digit) reversal until a
  palindrome appears.

  It is unknown if this process terminates for all integers.  For
  example, for 196, it appears not to, but no proof, to our
  knowledge, exists for nontermination.  The radix used is important.
  For bases that are powers of 2, it can be proved that there are
  integers for which the process does not terminate in a palindrome.
